-- STORAGE RLS POLICIES FOR LOGO/FAVICON UPLOAD
-- =====================================================
-- This fixes the "new row violates row-level security policy" error
-- when uploading logo/favicon to Supabase Storage
-- =====================================================

-- Step 1: Verify the 'content' bucket exists
SELECT * FROM storage.buckets WHERE name = 'content';

-- If no rows returned, create the bucket:
-- INSERT INTO storage.buckets (id, name, public)
-- VALUES ('content', 'content', true);

-- Step 2: Drop ALL existing policies first to avoid conflicts
DROP POLICY IF EXISTS "Authenticated users can upload brand assets" ON storage.objects;
DROP POLICY IF EXISTS "Authenticated users can update brand assets" ON storage.objects;
DROP POLICY IF EXISTS "Authenticated users can delete brand assets" ON storage.objects;
DROP POLICY IF EXISTS "Public can view brand assets" ON storage.objects;
DROP POLICY IF EXISTS "Authenticated users can list brand assets" ON storage.objects;

-- Step 3: Create policies for brand-assets upload

-- Policy 1: Allow authenticated users to INSERT (upload) files to brand-assets folder
CREATE POLICY "Authenticated users can upload brand assets"
ON storage.objects FOR INSERT
TO authenticated
WITH CHECK (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo/%' OR name LIKE 'brand-assets/favicon/%')
);

-- Policy 2: Allow authenticated users to UPDATE (replace) files in brand-assets folder
CREATE POLICY "Authenticated users can update brand assets"
ON storage.objects FOR UPDATE
TO authenticated
USING (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo/%' OR name LIKE 'brand-assets/favicon/%')
)
WITH CHECK (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo/%' OR name LIKE 'brand-assets/favicon/%')
);

-- Policy 3: Allow authenticated users to DELETE files in brand-assets folder
CREATE POLICY "Authenticated users can delete brand assets"
ON storage.objects FOR DELETE
TO authenticated
USING (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo/%' OR name LIKE 'brand-assets/favicon/%')
);

-- Policy 4: Allow public SELECT (view) on brand-assets (for displaying images)
CREATE POLICY "Public can view brand assets"
ON storage.objects FOR SELECT
TO public
USING (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo/%' OR name LIKE 'brand-assets/favicon/%')
);

-- Policy 5: Allow LIST operation for authenticated users (needed for auto-delete)
CREATE POLICY "Authenticated users can list brand assets"
ON storage.objects FOR SELECT
TO authenticated
USING (
  bucket_id = 'content'
  AND (name LIKE 'brand-assets/logo%' OR name LIKE 'brand-assets/favicon%')
);

-- =====================================================
-- VERIFICATION QUERIES
-- =====================================================

-- Check all policies on storage.objects
SELECT
  schemaname,
  tablename,
  policyname,
  permissive,
  roles,
  cmd
FROM pg_policies
WHERE tablename = 'objects'
AND schemaname = 'storage'
AND policyname LIKE '%brand assets%';

-- Test if you can access the bucket
SELECT * FROM storage.objects WHERE bucket_id = 'content' LIMIT 5;

-- =====================================================
-- TROUBLESHOOTING
-- =====================================================

-- If still getting RLS errors, check:

-- 1. Are you logged in?
SELECT auth.uid();

-- 2. Check RLS is enabled
SELECT tablename, rowsecurity
FROM pg_tables
WHERE schemaname = 'storage'
AND tablename = 'objects';

-- 3. Check bucket is public
SELECT * FROM storage.buckets WHERE name = 'content';
